Okay so it's 100mdef given to the target
100mdef? Where'd you figure that out O_o .. The effect says "bonus bNoMagicDamage,100" as in success of that effect is 100%. Then the other bonus "bonus bUseSPrate,100" which again means increase sp usage by 100% (AKA Double). So yeah.. where did you get 100 magdef from?
